I've installed the mod, but I only get the AJAX Image Swapper menu item under Configuration. There is no AJAX Image Swapper Manager unter Catalog.

I looked a the sql_installer.sql. there is not statement to add the AJAX Image Swapper Manager. See below:

Code:
DROP TABLE products_attributes_images;

CREATE TABLE products_attributes_images (
    image_id INT NOT NULL AUTO_INCREMENT,
    products_attributes_id INT NOT NULL,
    image_path VARCHAR(255),
    image_title VARCHAR(255),
    image_sort_order INT,
    PRIMARY KEY(`image_id`)
);

INSERT INTO configuration_group
(configuration_group_id, configuration_group_title, configuration_group_description, sort_order, visible)
VALUES (NULL, 'AJAX Image Swapper', 'Config options for AJAX Image Swapper', '1', '1');

UPDATE configuration_group SET sort_order = last_insert_id() WHERE configuration_group_id = last_insert_id();

SELECT @last_id :=last_insert_id() FROM configuration_group;

INSERT INTO configuration 
(configuration_id, configuration_title, configuration_key, configuration_value, configuration_description, configuration_group_id, sort_order, date_added)
VALUES 
('', 'Small Image Height', 'IMAGE_VIEWER_SMALL_IMAGE_HEIGHT','75','The height of small images in AJAX Image Swapper, shown as thumbnails. Default 75.', @last_id, 1, now()),
('', 'Small Image Width', 'IMAGE_VIEWER_SMALL_IMAGE_WIDTH','75','The height of small images in AJAX Image Swapper, shown as thumbnails. Default 75.', @last_id, 5, now()),
('', 'Medium Image Height', 'IMAGE_VIEWER_MEDIUM_IMAGE_HEIGHT','300','The height of medium images in AJAX Image Swapper. Default 300.', @last_id, 10, now()),
('', 'Medium Image Width', 'IMAGE_VIEWER_MEDIUM_IMAGE_WIDTH','300','The width of medium images in AJAX Image Swapper. Default 300.', @last_id, 15, now()),
('', 'Number of Images Shown', 'IMAGE_VIEWER_IMAGES_NUM','3','Number of images shown in AJAX Image Swapper', @last_id, 20, now());
Is there something wrong with my downloaded mod?
